VACUUM Error?

[Fabrice.Sznajderman@xxxxxxxxxxxx]

Hello,


I executed a Vacuum on my Postgres database.
You can see the command line : /vacuumdb
-f -z -v -d ccm > /tmp/vacuum.txt 2> /tmp/vacuumError.txt  I
used  performed the vacuum.

But I had error :"ERROR:  Parent
tuple was not found
vacuumdb: vacuum  ccm failed"
 each time I am executed the vacuum

have you any idea about this error?
And may be any solution ?

Thanks in advance,

best regard,

Fabrice
